A material-lifting vertical shaft planetary mixer

Abstract

The invention provides a lifting type vertical shaft planetary mixer, comprising: a base, a mixing drum, a stirring frame and a planetary mixer, columns are respectively arranged at both ends of the base, guide rods are arranged inside the columns, and a material lifting motor is arranged on the columns One end of the lifting shaft is connected to the lifting motor through a transmission system, and the other end of the lifting shaft is connected to a lifting crank; the two ends of the stirring frame are respectively slid with the guide rod through the sliding holes, and the The upper sides of the two ends are respectively hinged with connecting rods, and the other end of the connecting rods is hinged with the lifting crank; the upper side of the middle part of the stirring frame is provided with a stirring drive device, and the lower side of the stirring frame is connected with a slewing bearing; the upper end of the planetary mixer Rotationally connected to the slewing bearing, the lower end of the planetary mixer extends into the mixing drum. The material-lifting column planetary mixer of the present invention can carry out material-lifting action, reduces the diameter-to-height ratio of the mixing cylinder, and can avoid segregation of the mixing material caused by the high linear velocity of the mixing blade during stirring.

Description

technical field [0001] The invention belongs to the technical field of concrete mixers, in particular to a material-lifting vertical shaft planetary mixer. Background technique [0002] A mixer is a necessary equipment for preparing concrete. Vertical shaft planetary mixer is a common type of concrete mixer. It mainly realizes the forced mixing of concrete mixture through the rotation and revolution of the planetary mixing tool during work. Due to many advantages such as strong stirring effect, no stirring dead zone, and good sealing performance, the vertical shaft planetary mixer has been rapidly popularized and developed. The existing vertical shaft mixer mainly relies on the movement in the circumferential direction to achieve uniform mixing during the mixing process, and lacks the forced lifting effect in the height direction, so that the ratio of the diameter to the height of the mixing cylinder is often large, and the loading of the mixer The capacity depends on the ...

Problems solved by technology

The existing vertical shaft mixer mainly relies on the movement in the circumferential direction to achieve uniform mixing during the mixing process, and lacks the forced lifting effect in the height direction, so that the ratio of the diameter to the height of the mixing cylinder is often large, and the loading of the mixer The capacity depends on the size of the mixing cylinder, so the larger the capacity of the vertical shaft mixer with a larger ratio of diameter to height, the more significant the diameter of the mixing cylinder, which makes it difficult to transport the finished mixer, making the size of the mixer limited. limit

At the same time, the larger the diameter of the mixing cylinder, the greater the linear velocity of the mixing knife during the revolution process, resulting in greater centrifugal force on the mixture, thus increasing the risk of segregation of the mixture during the mixing process
